I'm trying to call an OpenCV function using P/Invoke method from C#, but I
get DllNotFoundException although the file exists on the disk.
I managed to call functions that are in the libcxcore.1.1.1.dylib library,
but I get the above exception for functions that are in
libhighgui.1.1.1.dylib (another opencv binary file).
Both files (libcxcore.1.1.1.dylib and libhighgui.1.1.1.dylib) are on the
same directory and I'm sure that the file libhighgui exists (I use "ls
The P/Invoke method is:
[DllImport(HIGHGUI_LIBRARY, EntryPoint = "cvNamedWindow")]
private static extern int _cvNamedWindow([MarshalAs(_stringMarshalType)]
String name, int flags);
I compiled opencv by myself from its latest SVN version, and managed to pass
all tests (include c++ examples that requires
Even if I have a problem in my library, DllNotFoundException is not the
correct exception to raise, because the file exists on the disk.
I run it from the latest version of MonoDevelop (Mac preview) and using Mono
188.8.131.52 on Mac OS 10.5.7
Can I step-by-step debug Mono from MonoDevelop to see when and why the
exception is raised?
Any ideas what else can cause a DllNotFoundException to be raised otherwise
than file doesn't exists?
Thanks in advance,
